Throttle Position Sensor: Testing and Inspection

NOTE: Perform the following test only when directed.

Resistance Inspection
1. Disconnect TP sensor connector.




2. Measure the resistance between TP sensor terminals 1 and 3 using an ohmmeter
- If not as specified, replace the TP sensor.
- If as specified, but TP V PID value or PCM terminal 89 voltage is out of specification, perform the "Circuit Open/Short Inspection".

Specification
3.2 - 4.8 kOhms

Circuit Open/Short Inspection
1. Disconnect the PCM connector.




2. Connect the SST (104 Pin Breakout Box) with the PCM disconnected.
3. Tighten the connector attaching bolt.

Tightening torque
7.9 - 10.7 N.m {80 - 110 kgf.cm, 69.5 - 95.4 in.lbf}

4. Check the following wiring harness for open or short (Continuity check).

Open circuit
- If there is no continuity, the circuit is open. Repair or replace the harness.
- TP sensor terminal 1 (harness-side) and 104 pin breakout box terminal 90
- TP sensor terminal 2 (harness-side) and 104 pin breakout box terminal 89
- TP sensor terminal 3 (harness-side) and 104 pin breakout box terminal 91

Short circuit




- If there is continuity, the circuit is shorted. Repair or replace the harness.
- TP sensor terminal 1 (harness-side) and power supply
- TP sensor terminal 1 (harness-side) and body ground
- TP sensor terminal 2 (harness-side) and power supply
- TP sensor terminal 2 (harness-side) and body ground
- TP sensor terminal 3 (harness-side) and power supply
